i have a question. I'm not getting fuel to either cylinder. it started out with just the rear cylinder now both injector are not opening. could a weak battery be the cause or maybe the computer. oh yea it's a 2001 rk. i took the injectors out and they had fuel in them and it seemed they just were not opening. plenty of fire to the cylinders. power to the injectors. please help. thank you

Have you checked fuel pressure at the injectors? Could be the fuel pump.

 

i have not. i'm not sure how to check the fuel pressure.

 

Thanks Piasspj i'm gonna have it chacked out

 

Swampy,
A good fully charged battery is never a bad thing, the only thing worse than a weak battery is a dead battery. If the battery is weak, charge it or replace it.

I was hoping some one else would jump in. Maybe try one of the technical forums.
I have manuals for my 2008 so these numbers may not be correct but the trouble shooting process should be similar.

Checking fuel pressure will require a gauge. My 2008 touring manual lists part numbers HD-41182 gauge and HD-44061 adapter (2 req'd). Also pressure as 55-62 PSI.
I think your system is different so these numbers may not be right.

I would expect an error code if the problem was with the ECM or injectors.
To check that the injectors are getting electrical input you will need a test lamp.
Again this information is for my 2008. For mine the tools required are HD-34730-2C test lamp, HD-41404-B Harness connector, HD-48637 Breakout Box.

I imagine that you can find less expensive tools than the H-D ones.
Good luck.

 

If you don't have a check engine light then problem is in the fuel system. Do you hear the fuel pump running? If it is check fuel pressue as piasspj said. If pump is not running then check Fuse, relay, fuel pump.

 

If you do not have a check engine lamp, it may still be electrical. The service manual gives a diagnostic on the EFI system.

 

Thanks for all the input. I am going to check all that stuff hopefully this weekend. I do appreciate the help, and thank you all very much. I'll post back on here the results. Oh had the battery checked and it is good.

 

it was the Fing battery. even with a battery charger hooked up it wasn't getting enough amps to the ecm. ahhh but at least its up and running now. Thanks for the help
